Description: If you're sitting for more than 8h per day, you may want a balance ball chair to improve your posture and work on core and lower-back muscles.
How sitting actively can change your life
We literally sit for up to half of our lives. Be in the office, in the classroom or just at home behind the computer desk, we spend an incredible chunk of our time sitting.
Of course, we do expect our spine to hold up our upper body weight all this time, and if we can help it, that will go a long way down the line.
